OBJECTIVE
Methotrexate (MTX) is an increasingly popular anti-rheumatic drug with its usefulness limited by toxicity, most commonly gastrointestinal (GI). The aim of the study was to study the effectiveness of the 5-HT3 receptor antagonist granisetron (GR) in the therapy of MTX-induced nausea.
METHODS
A single-blind 8 week pilot study with random allocation to either GR 1 mg or prochlorperazine (Stemetil; PCh) 10 mg was undertaken in 13 patients who were taking or had taken MTX for either rheumatoid arthritis (10) or psoriatic arthritis (3).
RESULTS
One in six patients treated with PCh completed the 8 week study compared to 7/7 treated with GR. After switching of symptomatic patients, 11 completed the study on GR and median improvement was by two grades (P < 0.001) with a significantly better visual analogue scale score for patient satisfaction compared to PCh.
CONCLUSIONS
Treatment with GR may be useful in establishing and maintaining some patients on MTX where GI toxicity would have precluded such therapy.
